Patented July 4, 1916.

Application filed October 11, 1915. Serial No. 55,285.

To all whom it may concern:

Be-it known that I, BARNEY H. SANDERS,

a citizen of the United States, residing at St- Louis, Missouri, have invented 'a certain new and useful Improvement in' Floor- Drains, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to floor'drains'of the -type that comprise a shield for preventing the water that enters the joint between the head or top portion of the drain and the surface of the floor in which the drainis set from travelingdown the outer side of the drain to the lower end thereof, and thus discoloring theceiling of the room over which the floor is located or undermining the foundation of the basement floor.

One object of my invention is to provide a floor drain of the general type mentioned which is more efiicient than the drains'of this type now in use,-

basin which is embedded in the floor to collect the seepage is provided with an integral portion to which the waste pipe or soil pipe is joined, thereby eliminating the possibility. of the seepage escaping from the shield into the floor, as is apt to occur when the shield is screwed onto the exterior of the portion of the drain to which the waste pipe cause a concrete floor is joined. 7

Another object is to provide a floor drain of the type mentioned, in which the head of the drain can be adjusted vertically with relation to the shield, so as to adapt the drain to floors of various thicknesses and also enable the head of the 'drain to be arranged fiush with the floor line at any time, either when the drain is first set, or after it has been in use for-sometime, in case the floor shrinks or becomes lower than the upper edge of the head of the drain.

Another object is to provide a floor drain of the type mentioned, in which the shield or basin is so designed that it will not tend to to crack at the point where it contacts with the rim of the shield.

Another object is to provide a floor drain in which the cap is of such a design that it can be adjusted downwardly, so as to close up the joint between the outer surface of same and the floor, in case said joint opens up or becomes abnormally wide, due to shrinkage. of the floor away from the head in that the shield or,

-preferred shape,

of the drain. And still another object is to provlde a floor drain of'the type mentioned, which is so designed that the opening or openings through which the seepage escapes from the shield can be cleaned easily,-by

simply rotating the adjustable head portion of the drain. 1

Other objects and desirable features of my-invention will be hereinafter pointed out. Figure 1 of the drawings is a vertical cross-sectional view of -a floor drain con-- structed in accordance with my invention, illustrating thedrain arranged in operative position in a floor; and Fig. 2 is a top plan vlew of the drain.

Referring to the drawings, which illustrate the preferred form of my invention, A designates the head of the drain, and B designates the shield or basin, said shield being embedded in the floor m at a point some distance below the top surface of the floor, as

shown in Fig. 1, so as to collect any water that seeps through the joint between the floor and the outer surface of the head of the drain. The head A is arranged centrally with relation to the shield or basin B and is adjustably connected to said shield so that it can be moved vertically with relation to the shield. The head A is substantially funnel-shaped, or, in other words, is provided with a tapered body portion 1 whose upper end merges into a cylindrical-shaped flange A is provided with the usual grill or grating .6 which may be connected to the head in various ways, such, for example, as by means of screws 7 that, are screwed into lugs 8 on' the inner side of the head A. The sleeve 3 on the head A is provided on its exterior with screw threads that cooperate with internal screw. threads 4* on the tubularshaped portion 4 of the shield, thereby enabling the head to be adjusted vertically is screwed, the shield hereinshown being with relation to the shield, so as to adapt the drain to floors of different thicknesses, or to enable the head to be set flush with the floor line. The water that seeps through the joint between the outer surface of the head A and the floor works downwardly over the outer surface of the head into the shield or basin B and then escapes from said shield into the waste pipe or drain pipe (not shown) which is connected to the tubular-shaped portion 4 on the shield.

In the form of my invention herein shown the tubular-shaped portion 4 is provided at its lower end with an internally screwthreaded portion 4; to which the drain pipe is connected, but I do not wish it to be understood that my invention is limited to a drain in which the waste pipe, soil pipe or trap is screwed into the portion 4 of the shield, as it is immaterial, so far as my broad idea is concerned, how the shield and waste pipe are connected together. The inter nally screw-threaded portion 4 of the part 4 of the shield is provided with one or more vertically-disposed grooves 9 and the sleeve 3 on the head A is provided on its outer surface with one or more vertically-disposed grooves 10, both the grooves being deeper than the screw threads which they intersect. The head A is preferably so arranged with relation to the shield B that the cooperating grooves 9 and 10 therein will line up, and

thus form passageways through which the seepage can escape from the shield into the drain pipe without liability of leaking into the floor, and thus discoloring the ceiling of the room arranged below the floor or undermining the foundation of the floor, as, for example, in case the drain is set in a basin of the floor. An annular groove 11 that is formed in the inner surface of the tubularshaped portion 4 of the shield between the internally screw-threaded portions 4} and 4 of same provides sutficient space for the seepage to escape from the vertical grooves 9 and 10, even when the head A is adjusted downwardly as far as it will go. In setting the drain it is preferable to fill the shield B with coarse granular material, as shown in Fig. 1, if the floor m is formed of concrete, so as to provide sufficient space for the seepage that collects in the shield.

A floor drain of the construction above described is 'more efficient than floor drains of this general type that are now in general use, owing to the fact that it is impossible for the seepage to escape from the shield, as the shield is provided with an integral portion in which the waste pipe, soil pipe or trap is joined. -As the head of the drain can be adjusted vertically with relation to the shield, the drain can beset in floors of. different thicknesses and still maintain the shield at the proper distance below the floor line. And still another advantage of constructing the drain in this manner is that the upper edge of the head can always be kept flush with the floor line. The fact that thehead A can be adjusted vertically and is provided with a tapered portion makes it possible to screw the head downwardly, and thus seal it firmly against the floor, in case the ioint between the outer surface of said tapered portion and the floor opens up, due to shrinkage of the floor. The horizontallydisposed flange 5 on the rim of the shield through said slots, and thus dislodge any "material that has collected in same.

, Having thus described my invention, what I claim, and desire to secure by Letters Patent, is: a

1. A floor drain consisting of a shield that is adapted to be embedded in a floor some distance below the top surface thereof, said shield being provided at its center with a screw-threaded opening, a depending tubular-shaped portion on said shield arranged concentric with relation tosaid opening and adapted to have a drain pipe connected to same, a vertically-adjustable head carried by said shield and provided with an externally-threaded sleeve that fits in the opening at the center of the shield, and means'for permitting the seepage that col.- lects in the shield to escape therefrom into the depending tubular-shaped portion on the shield to which the drain pipe is connected. 2. A floor drain consisting'of a shield provided with an integral portion to which a a drain pipe is adapted to be connected, said portion being provided at its upper mounted, and an annular recess formed in the inner surface of the portion of the shield to which the 'wastepipe is connected at a point'below the internal screw threads on said portion.

3. A floor drain consisting of a shield having a rim that is providedat its upper edge with an approximately horizontallydisposed flange, an integral depending por- 1,189,742 i i gt operating grooves formed in the outer surv face of the sleeve on said head and in the inner surface of the depending portion of 15 the shield that surrounds said sleeve.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses, this seventh day of October 1915.
